Asbestos is commonly found in buildings and structures built before what year?

Answers

Answer 1

Answer: Asbestos is commonly found in buildings and structures built before the year 2000. This is because it was around this time that it was discovered that inhaling asbestos particles can lead to very serious diseases. It is a material found in many parts of a building or any infrastructure. A total ban of the material was implemented in 2000.

Ammonia is produced by the following reaction. 3H2(g) + N2(g) ---> 2NH3(g) When 7.00 g of hydrogen react with 70.0 g of nitrogen, hydrogen is considered the limiting reactant because

Answers

To determine the limiting reactant, we first calculate the number of moles of the reactant.

7.00 g H2 ( 1 mol / 2.02 g ) = 3.47 mol H2
70.00 g N2 ( 1 mol / 28.02 g) = 2.50 mol N2

From the balanced reaction, we see that there is a 3 is to 1 ratio of the reactants. So, for every 3 moles of H2 we need 1 mole of N2. Given the amount of reactant, for 2.50 moles of N2 we need 7.5 moles of H2 which obviously we have a lesser amount. Hydrogen is the limiting reactant.

The correct answer is A

Cause and effect of local winds?

Answers

Local winds are caused by the different surfaces on each lands which heat up differently based on climate and its temperature. This is a complete difference in temperature, and therefore causes a difference in pressure as well. This is capable of causing the air to move differently based on the actual location.

The incomplete breakdown of fat that occurs when carbohydrates are not available produces

Answers

Answer;

Ketone bodies

Explanation;

Ketone bodies are produced by the liver and used peripherally as an energy source when glucose is not readily available.
They are produced from acetyl-CoA, mainly in the mitochondrial matrix of liver cells when carbohydrates are so scarce that energy must be obtained from breaking down of fatty acids.
Tissues that can use fatty acids can generally use ketone bodies in addition to other energy sources. The exceptions are the liver and the brain.

Which radioisotope has the fastest rate ofdecay?
(1) 14C
(2) 37Ca
(3) 53Fe
(4) 42K

Answers

The correct answer is 2. 37Ca.

The fastest rate of decay in radioisotope is 37Ca. Another name for radioisotope is radioactive of isotopes which are of given element.

The different number of neurons and the same number of protons are present on the same element with different isotopes. Radioisotopes are considered to have an unstable combination of neutrons and protons.

The correct answer to this question is (2) 37Ca . The radioisotope that has the fastest rate of decay is 37Ca. Radioisotope or also known as radioactive isotopes of a given element. Same number of protons but different number of neurons are present on different isotopes of the same element. They are considered as atoms that have unstable protons and neutrons combination.

The amount of energy a person can consume throughout the day without gaining weight is extremely dependent onA. hunger.
B. appetite.
C. culture.
D. activity level.

Answers

I'm quite sure it's activity level. One other thing that could've been said is metabolism, but that isn't there. However, food is consumed for the body to have energy, and without that energy we wouldn't be able to function. And when we let that intake of food settle, it's stored as fat. But because of activity level, we are capable of burning those calories.
